During the Side Quest "Curry for What Ails You", Lester wants some Goron Spice so he can make Curry Rice and will trade Link some Hylian Rice for Goron Spice. Link can continue to trade Goron Spice to Lester for Hylian Rice after completing the quest, though this is unnecessary as Hylian Rice is fairly common ingredient to come by while Goron Spice is much rarer. In fact it is essentially an unfair trade as Link is trading a much rarer item that must be purchased for an easily obtained item that can be acquired by cutting grass in certain regions.
